Dandy’s Peat Free Summermix Compost - The Perfect Boost for Your Garden during hot summer months.

Our Peat Free Summermix Compost Garden Mulch is the perfect blend of rich, screened organic compost and composted bark mulch fines - making it super easy to work with and full of moisture retaining properties.  It is packed full of nutrients ideal for plants, flowers or veggies and can be used any time during the summer months.

Allow the compost to do the hard work and use as a mulch over your existing borders to replenish the soil or gives great results when mixed into new topsoil too!  We advise giving your borders a good soak first before laying down as a mulch. 

We can supply you with 3 sizes of bulk bag:

  • Jumbo Bulk Bag which contains approx 1000ltrs (one cubic metre)
  • Standard Bulk Bag contains about 750ltrs (same as most builders merchants)
  • Half Bulk Bag contains approx 500ltrs

Small Handy Bags are approximately 50ltrs and the perfect option if you want a small quantity or if you have access issues and will need to carry through your house or over any walls etc.

Transform your garden into a thriving oasis with our premium Summermix Compost. Designed to meet the unique needs of your plants during the warm summer months, this carefully crafted blend by Dandy's is the secret to achieving lush, vibrant growth.

Quantity Calculations

Topsoil and Sand

Length (m) X Width (m) = m2 

m2 X 1.2 X Depth (inches)... then divide your total by 36 = tonnes required

Bark, Mulch and Compost

Length (m) X Width (m) = m2 

m2 x 0.05 = cubic metres per 2 inch/50mm depth

Garden Lawn Turf

Length (m) X Width (m) = amount of rolls needed.  We advise that you order 10% extra so that you have plenty for offcuts.

Natural Stone Paving

Length (m) X Width (m) = m2 you need.  Our packs are 15.25m2.

Gravel and Slate

Length (m) X Width (m) = m2 

m2 x 0.04 = tonnes per 1 inch/25mm depth


Use the Gravel Calculator then multiply by 1.25 (= tonnes per inch)


1 tonne = 1000kgs / 1 Jumbo Bag

1 cubic metre = 1000ltrs / 1 Jumbo Bag


Samples are sent with Royal Mail 2nd class service so please allow 3 to 5 working days (please allow extra during Royal Mail Strikes).

Samples are chosen at random and naturally occurring products may vary slightly in shade and particle size, from load to load.

This is a small amount of product that will fit in your hand, approx 100gms per sample.

Product Disclaimer


We do not chemically treat our products for weeds. Weeds thrive in warm, wet weather and especially in very fertile soils and composts like our own. Although every care is taken to remove weeds during our screening process we can not guarantee that weed seeds are not present in the soil or compost that you receive. To keep your topsoil organic we suggest pulling up common weeds, when and if they appear, instead of using chemical weed-killers. Or purchase some of our anti-weed prevent membrane and some gravel or mulch, for an easy weed-free garden!

Gravel/Stone Size & Colour

Images are for representation only.  All products that Dandy’s supplies are naturally occurring products and may have slight variations in colour, size and content, individual rocks, stones or cobbles made be broken or misshaped because of this. Sizes of products specified are approximate and can vary.  Naturally occurring products such as slate, natural stone paving or gravel are sourced from quarries and so can often differ in appearance slightly from load to load.

Summermix mulch

Not only did our plant beds look good once dressed with this mulch, once drawn down into the soil, we'll have a healthier soil to support our planting. Glad we bought it.

Happy borders!

Great communication for the delivery, which arrived at the estimated time. The delivery driver was really helpful and was able to place the bulk bag in a convenient spot of my choice within the limits of the reach of the crane. The product itself is a great mix of compost fines and manure and was steaming in the middle! There were a few bits of glass and plastic, but not in any quantity to cause concern in the context of the quantity ordered. Time will tell how the product improves the area it was placed, but I think the plants look happy and ready for some friends to be added 😉 with the added bonus that I just love the smell! Based on my experience to date, I would not hesitate to order a similar product from Dandys again.
